New Study Finds Nanoplastics in Artery Plaque
Linked to Stroke and Heart Attack Risk

A groundbreaking new study has revealed that nanoplastics-ultra-tiny fragments of plastic-are accumulating in the fatty plaque that clogs arteries supplying blood to the brain. This discovery may reshape our understanding of stroke and heart attack risks, highlighting plastic pollution as a potential new threat to cardiovascular health.

Key Findings from the Study

Researchers analyzed carotid artery tissue from 48 adults, including stroke survivors, asymptomatic patients with artery plaque, and healthy donors
‍
‍Plaque from stroke survivors contained 51 times more micronanoplastics than healthy artery walls.

Even asymptomatic plaque had 16 times more than healthy tissue.

These nanoplastics are so small-less than 1,000 nanometers wide-that they can infiltrate cells and tissues undetected.

How Do Nanoplastics Get Into Our Bodies?

Nanoplastics come from the breakdown of larger plastic items in the environment. They enter the food chain through contaminated water and food, eventually making their way into the human body. Once inside, their tiny size allows them to penetrate deep into organs and tissues, including blood vessels.

Why Does This Matter for Stroke and Heart Health?

While the findings are preliminary and more research is needed, experts say this could open a new chapter in understanding-and potentially preventing-stroke and heart attack. As Dr. Karen Furie of Brown University noted, plastic exposure may become a modifiable risk factor for cardiovascular disease in the future.

Takeaway for Readers
‍Micro- and nanoplastics are now found throughout the environment-and in our bodies.
This study links high levels of nanoplastics in artery plaque to a greater risk of stroke and heart attack.
Reducing plastic pollution and exposure could become a new focus for heart health in years to come.

Stay tuned as scientists continue to unravel how the plastics we use every day may be affecting our most vital organs.
